Features

The T model is an industrial-duty trolley door opener, as manufactured by The Chamberlain Group and is for use on standard lift sectional doors. It is rated for more than 12 cycles per hour during peak periods.

Maintenance Alert SystemTM establishes a routine maintenance schedule based on the number of cycles or calendar date. Includes self‑diagnostic system that allows you to troubleshoot up to eight different error codes

Timer‑to‑close allows programming in 1‑sec or 15‑sec increments and permits timed automatic door closure after the door reaches the fully open position; requires monitored photosensors, either CPS‑U, CPS‑UN4, or a 4‑wire edge, using the CPS‑EI edge interface

Thermal motor overload can be easily reset from the 3‑button floor level control station

The timer‑to‑close automatically closes the door - programmable in 1‑second or 15‑second increments.

The mid‑stop stops the door at programmable mid‑stop during open travel.

The maximum run timer signals the door to reverse or stop if closing time exceeds maximum by more than 10 seconds.

Maintenance alert system (5 000 to 10 000 cycles).

UL and CSA listed.

2‑year warranty.

Standard security systems

Your security, our priority!

CPS® Commercial protector system®

The presence of primary entrapment protection is standard CPS‑U for all modes. Primary entrapment protection devices are monitored continuously to ensure safe operation of the door and limit door opener functionality should an obstruction be detected or in the event of device failure. Optional LiftMaster monitored entrapment protection devices, CPS‑UN4, CPS‑RPEN4, and CPS‑EI, are designed to work in conjunction with LiftMaster commercial door openers to provide enhanced door safety and a broad range of modes and features to end users. Either monitored photo‑sensor or monitored 4‑wire sensing edge (in conjunction with the CPS‑EI Edge Interface) protection may be selected, but one must be detected by the LiftMaster Logic 4.0 or Medium‑Duty Logic circuit board in order to unlock full functionality.

Warning

Garage doors and garage door openers can be dangerous if not installed and verified by a professional and not used properly. Children must be supervised by an adult when they are inside or in proximity of the garage.
